Applications

This versatile OM4 MTP trunk cable is the ideal solution for structured cabling backbones within the data center. In practice, it is used for establishing high-bandwidth connections between main distribution areas (MDAs) and equipment distribution areas (EDAs). It is perfect for direct 40G/100G equipment-to-equipment links and for connecting high-density fiber patch panels or MTP® cassettes, enabling seamless migration paths from 10G to 40G and 100G networking speeds.

Specifications

Advantages

The primary advantage of using a factory-terminated 12 fiber MTP® OM4 trunk cable is its reliability and speed of deployment. It eliminates the potential errors of field termination, ensuring consistent quality. As a result, installation time and labor costs are significantly reduced. The Elite Low Loss connectors provide a superior optical link budget, which is critical for maintaining signal integrity across multi-connection high-speed channels.

Furthermore, its Plenum (OFNP) rating guarantees compliance with strict fire safety codes, making it the required choice for routing through ducts and air-handling spaces. The high-density nature of the MPO/MTP® connector saves significant pathway and rack space compared to traditional cabling. Thus, this cable is a future-proof investment that simplifies cable management and supports network growth for years to come.

FAQ (Technical & Product Questions)

1. What is a 12 fiber MTP trunk cable used for?

A 12 fiber MTP® OM4 trunk cable is primarily used for high-density backbone cabling in data centers. It creates a high-bandwidth link between switches, servers, or MTP® cassettes, and is optimized for running 40G and 100G parallel optic applications like 40GBASE-SR4.

2. What is the difference between Polarity A, B, and C for MTP® cables?

Polarity defines the fiber mapping between the two MTP® connectors. This cable uses Polarity B (Cross-Connect), where the fiber positions are reversed (1-to-12, 2-to-11). This is the standard for direct connections between 40G/100G SR4 transceivers. Polarity A is straight-through (1-to-1) and Polarity C uses flipped pairs.

3. Why is a Plenum (OFNP) rating important for an OM4 trunk cable?

A Plenum (OFNP) rating is the highest fire safety rating for fiber optic cables. It indicates the cable has low-smoke and low-flame characteristics, making it safe and code-compliant for installation in plenum air spaces, such as above suspended ceilings or under raised floors.

4. What is the advantage of an Elite Low Loss MTP® connector?

An Elite Low Loss MTP® connector is a premium version with significantly lower insertion loss (typically under 0.35dB) compared to standard connectors (0.6dB or higher). This provides a better link budget, ensuring higher performance and reliability, especially in high-speed 40G/100G networks with multiple connection points.

5. Can this MTP OM4 cable support 40G and 100G applications?

Yes, absolutely. This OM4 MTP trunk cable is specifically designed for high-speed applications. It is ideal for 40GBASE-SR4 and 100GBASE-SR10, which both utilize 8 of the 12 fibers within the MPO/MTP® connector to transmit and receive data.

6. How do I choose between MTP® Male and Female connectors?

The choice depends on what you are connecting to. Male connectors have two alignment pins, while Female connectors have holes. Generally, the transceiver (like a QSFP+) has pins, so you need a Female connector on the cable. For cable-to-cable connections via an adapter, you need one Male and one Female connector.

7. What is the difference between MTP® and MPO connectors?

MPO is the generic industry standard for this style of multi-fiber connector. MTP® is a brand name for US Conec’s high-performance MPO connector, featuring superior mechanical and optical performance. This cable uses genuine MTP® connectors, ensuring higher durability and more reliable connections.

8. What is the bend radius for this OM4 MTP® cable?

The cable is built with bend-insensitive OM4 fiber, allowing for a tight minimum bend radius of 7.5mm without significant signal loss. This makes the 12 fiber MPO/MTP® patch cord more flexible for routing in crowded racks and cable trays without compromising performance.
